Definitions

  • the present invention relates to an apparatus for forming plastic preforms into plastic containers, and more particularly to a stretch blow molding machine.
  • a stretch blow molding machine In the prior art, it is generally known to produce containers by blow molding, wherein initially thermoplastic preforms z. B. of polyethylene terephthalate (PET) are heated in a heating station, so that they can then be deformed in a blow mold by blow molding or by stretch blow molding so as to create a desired container shape.
  • PET polyethylene terephthalate
  • the preforms z. B. transported on a link chain with mandrels.
  • the heated preforms are then fed by means of a transfer device to a blowing wheel, on which are distributed over the circumference several blow molds.
  • the blow molds have two unfoldable mold halves and a mold bottom, in which recesses corresponding to the shape of the container to be manufactured, are formed.
  • the unfolded blow mold After a preform has been fed to the unfolded blow mold, the unfolded blow mold is closed and the container is produced by blow molding or stretch blow molding. The blow mold then opens again and the finished container passes through an outlet star to the container output.
  • a stretch rod is usually used to stretch the plastic preform in its longitudinal direction.
  • the WO 2009/144664 A2 shows a plant for blow molding plastic containers from respective preforms, comprising a plurality of mold units each having a mold for blow molding at least one container and at least one draw bar which moves under the action of a drive means to axially deform a respective preform;
  • the drive device comprises for each mold unit a drive motor coupled to the drawbars of the mold unit itself.
  • the WO2006 / 108380 A2 shows a method for positioning a component in which a fluid drive moves the component along a guide, wherein the component is additionally positioned by a linear electric drive.
  • the electric motor must be dimensioned considerably larger in order to compensate for the permanent counterforce. These higher losses often require additional cooling. These additional measures make the system more expensive and also make it less economical.
  • the present invention is therefore based on the object to make such stretch blow molding more economical.
  • An inventive device for expanding plastic preforms to plastic containers has a blow mold, within which the plastic preforms are expandable to the plastic containers. Furthermore, a supply device is provided in order to supply the plastic containers with a gaseous medium and in particular with air for their expansion. In addition, a stretch rod is provided to stretch the plastic preforms along the longitudinal direction thereof, wherein a drive motor in the form of an electric motor is provided, which generates a forward movement of the stretch rod in the longitudinal direction thereof for stretching the plastic preform.
  • the device in addition to the electric motor, the device has a force compensation device which compensates at least partially and at least temporarily for a force acting on the electric motor or the stretching rod by an internal pressure of the gas in the container. Therefore, while in the prior art, the electric motor itself is used to convert this force into electrical energy, for example, in that it goes into a regenerative mode during the backward movement of the stretch rod or applies a standstill torque, it is proposed to provide an additional force compensation device, which said force acting on the electric motor at least reduces.
  • the forward movement of the stretch rod is understood to mean that movement which stretches or elongates the plastic preform.
  • the compensation force acts in the direction of the expansion movement of the stretch rod.
  • a regenerative operation of the electric motor is at least temporarily prevented and particularly preferably completely prevented in a backward movement of the stretch rod.
  • the heat generated in the generator operation heat developments can be prevented. So it is possible that the electric motor is decoupled in the backward movement, but it would also be possible that he is driven, but not working in generator mode, ie in particular does not generate electricity in any way.
  • the force compensation device is independent of the electric motor.
  • the device has a threaded spindle drive or a linear motor for moving the stretch rod. It is possible that a motor rotates the stretch rod itself and moves in this way with respect to a threaded nut, but it would also be possible that the drive reversely rotates a fixed in the longitudinal direction of the stretch rod threaded nut and thus causes the movement of the stretch rod.
  • other drives such as linear motors, servo drives with a motion translation by means of rack and gear or belt ratios would be conceivable.
  • a linear stretching movement is generated by a screw spindle, which requires a certain number of revolutions, for example between 5 and 15, or between 8 and 12 revolutions for the entire stretching movement.
  • the device is designed such that the energy which is generated by the internal pressure in the container, not lost but is cached.
  • a pneumatically operating force compensation device is provided as a force compensation device.
  • a piston connected to the stretching rod it would be possible for a piston connected to the stretching rod to be subjected to the blowing pressure.
  • the force compensation device can use the internal pressure within the container for force compensation.
  • the force compensation device has a piston element which is coupled to the stretch rod and which moves relative to a piston receptacle.
  • a connecting line is provided which connects the interior of the container with a ensellenden piston receiving, so that the blowing pressure in the container interior can be guided on the piston.
  • said piston has the same cross-section as the stretch rod, so that upon application of the same internal pressure of the container, an equilibrium of forces arises.
  • the pressure applied to the piston surface is advantageously the surface of the stretch rod or the lower surface facing away, so that in this way a lifting of the forces is particularly efficient.
  • a corresponding device has a plurality of blowing stations or a plurality of devices for expanding plastic preforms to plastic containers. It is possible that the aforementioned piston to generate the opposing force of all stations are summarized on a loop. This loop can be kept at a specified pressure level via pressure regulators. So it is possible that, for example, the stretch rod is balanced in an extended state. If one of the stretch rods drives in, then the stretch rod is simultaneously extended at another station, the stretching process being assisted by the displacement of the air.
  • the force compensation device acts such that before the end position of the stretch rod d. H. the situation in which the stretch rod is almost retracted only with a certain acceleration, for example, a "acceleration" of a maximum of -1g (deceleration) is braked. This deceleration force can be caused by the weight of the drawing carriage. It would also be possible to switch off the electric motor shortly before the deceleration, in which case the stretching cylinder preferably ascends to a mechanical damping system. In principle, it would be possible to use this invention with all variants of electric stretching systems, for. As linear motors, spindles, spindle nuts, belts and gears.
  • the device has a pressure supply line and this pressure supply line is advantageously combined with a plurality of compressed air supply lines in a ring line.
  • the ring line to a pressure control.
  • this pressure supply line is preferably coupled to the piston elements or is in fluid communication therewith.
  • a plant for forming plastic preforms into plastic containers may comprise a plurality of devices of the type described above, and these individual devices may each comprise said pressure supply lines.
  • the present invention is further directed to a method of expanding plastic preforms into plastic containers.
  • the plastic preforms are expanded within a blow mold to the plastic containers and thereby the plastic preforms with a feeding a gaseous medium for their expansion fed and the plastic preforms are stretched with a stretch rod along the longitudinal direction.
  • a drive motor in the form of an electric motor is provided, which generates a forward movement of the stretch rod in the longitudinal direction for stretching the plastic preform.
  • a force acting on the electric motor produced by the internal pressure of the gas in the container is compensated at least partially and at least temporarily by a force compensation device acting in addition to the electric motor.
  • This force compensation device preferably relieves the load on the electric motor or, in particular, reduces the forces acting on the electric motor during a backward movement of the stretch rod. It is advantageously avoided in this way that the electric motor passes into a (heat-generating) generator operation.
  • Fig. 1 shows a rough schematic representation of a system according to the invention for expanding plastic preforms to plastic containers.
  • the reference numeral 52 denotes a heating device, such as a furnace, which pass through the plastic preforms and which heats the plastic preforms.
  • the plastic preforms are transferred to the actual blower 54, which has a plurality of devices which expand the plastic preforms to plastic containers.
  • the plastic preforms are guided isolated. Therefore, a transport device is provided which promotes the plastic preforms through the blower 54.
  • a so-called blowing wheel can be provided, on which a plurality of blowing stations is arranged, these blowing stations therefore moving on a circular path. This movement can be carried out continuously or preferably clocked.
  • Fig. 2 shows a side view of a device 1 according to the prior art for converting plastic preforms to plastic containers.
  • this device has mold carriers 15, in the interior of which (not shown) a blow mold is arranged.
  • This blow mold forms a cavity within which the plastic preforms are subjected to compressed air, in order to be expanded in this way.
  • the reference numeral 4 designates a feeder such as a tuyere to supply the compressed air to the plastic preforms.
  • the reference numeral 6 designates a stretching rod, which moves in any case in the longitudinal direction L of the container in order to stretch plastic preforms in their longitudinal direction during the expansion process.
  • the drive of this stretch rod 6 can be done for example via a drive 9, here a pneumatic drive.
  • the reference numeral 5 denotes a carrier on which the stretching bar arrangement is arranged.
  • reference numeral 46 refers to a stretch carriage on which the stretch rod 6 is arranged.
  • the reference numeral 36 denotes a blast carriage which (see. Fig. 3b ) drives the tuyere to the container 10 during the expansion process.
  • FIGS. 4a and 4b show more detailed representations of an inventive device for expanding plastic containers.
  • the reference numeral 8 refers to an electric motor, which is controlled by a controller 45, and which serves to move the stretch rod 6.
  • the reference numeral 42 denotes a heat sink which is for cooling the electric motor 8 and the controller 45 and the reference numeral 38 denotes a bearing block.
  • a stretching carriage 46 can here move along the arrow P1, its movement being bounded at the top by a stop 44.
  • the reference numeral 32 denotes a driver for carrying a blow carriage 36. This blast carriage 36 is moved here via a guide roller 34 and a (not shown) guide curve.
  • the reference numeral 4 again indicates (partially shown), a blowing piston or a blowing nozzle which serves to expand the plastic containers 10.
  • the reference numeral 48 denotes the valve block, via which the compressed air supply is controlled in the containers. To reduce noise, a silencer 35 (see. Fig. 4b ).
  • the Fig. 5a shows a further embodiment of a device according to the invention.
  • a servomotor 8 is provided which causes the movement of a stretch rod 6 in a container 10 in and out of this.
  • the blowing nozzle 4 can be seen, which acts on the plastic preform with the blowing air.
  • a piston 16 is provided here, which moves with the stretch rod 6 and which is displaceable relative to a piston seat 18. Also, this piston seat 18 is acted upon during the blowing process with the blowing pressure and causes the expansion of the container that the movement of the stretch rod is reinforced downward. Once the container is fully stretched, but has built up pressure in its interior, the stretch rod 6 would be pushed by this pressure upwards.
  • a pressure has formed in the piston receptacle 18, which counteracts the first-mentioned pressure. If the lower end of the stretch rod 6 and the upper end of the piston 16 have the same cross section, these pressures are also lifted each other up.
  • About the compressed air supply line 26 is supplied on the one hand via the line section 23 piston receiving 18 with compressed air and also on the line section 25, the container 10. In the in Fig. 5b embodiment shown, a separate control of the piston seat 18 and the container 10 would be possible.
  • the piston 16, the piston seat 18 and the pressure supply line 23 form the force compensation device 20 here.
